A much valued tool that also brings ethical dilemmas - a qualitative study of Norwegian midwives' experiences and views on the role of obstetric ultrasound.

BACKGROUND: Midwives are the main providers of routine antenatal care services including the routine ultrasound examination in Norway. The ultrasound examination can be perceived by expectant parents not only as a medical examination but also as a social event facilitating attachment to their fetus. This study explores Norwegian midwives' experiences and views on the role of ultrasound in clinical management of pregnancy. METHODS: A qualitative study design was applied. Twenty-four midwives who all performed obstetric ultrasound examinations were recruited for focus group discussions and individual interviews. Data collection took place in 2015 in five hospitals in two different regions of Norway. Data were analyzed using qualitative content analysis. RESULTS: Midwives described obstetric ultrasound examinations as very valuable although doing ultrasounds placed high demands on their operational and counselling skills. Increasing requests for ultrasound from pregnant women were mentioned. Advancements in ultrasound diagnosis were considered to have put the fetus in the position of a patient, and that pregnant women declining ultrasound could be viewed as irresponsible by some health professionals. Ethical concerns were raised regarding the possibility of pregnancy termination when fetal anomalies were detected. Fears were also expressed that prenatal diagnoses including those following ultrasound, might create a society where only 'perfect' children are valued. However, participants stressed that their intention in performing ultrasound was to optimize pregnancy outcome and thereby assist expectant couples and their unborn children. CONCLUSIONS: Midwives in Norwegian maternity care services describe obstetric ultrasound as very valuable, playing a central role in pregnancy management by optimizing pregnancy outcomes. Although high demands are placed on operators' technical skills and counseling, midwives described performing obstetric ultrasound as very satisfying work. However, midwives believed that expectant parents' approach to the ultrasound examination, both its medical value and the precious images obtained of the fetus, could put extra strain on the midwives performing ultrasounds. The potential of ultrasound to detect fetal anomalies and the possibility that this may lead to termination of pregnancy, seemed to create some ambivalent feelings in midwives towards its use.

Norwegian obstetricians' experiences of the use of ultrasound in pregnancy management. A qualitative study.

OBJECTIVE: To explore obstetricians' experiences and views of the use of obstetric ultrasound in clinical management of pregnancy. METHODS: A qualitative interview study was undertaken in 2015 with obstetricians (N = 20) in Norway as part of the CROss Country Ultrasound Study (CROCUS). RESULTS: Three categories developed during analyses. 'Differing opinions about ultrasound and prenatal diagnosis policies' revealed divergent views in relation to Norwegian policies for ultrasound screening and prenatal diagnosis. Down syndrome screening was portrayed as a delicate and frequently debated issue, with increasing ethical challenges due to developments in prenatal diagnosis. 'Ultrasound's influence on the view of the fetus' illuminated how ultrasound influenced obstetricians' views of the fetus as a 'patient' and a 'person'. They also saw ultrasound as strongly influencing expectant parents' views of the fetus, and described how ultrasound was sometimes used as a means of comforting women when complications occurred. 'The complexity of information and counselling' revealed how obstetricians balanced the medical and social aspects of the ultrasound examination, and the difficulties of 'delivering bad news' and counselling in situations of uncertain findings. CONCLUSION: This study highlights obstetricians' experiences and views of ultrasound and prenatal diagnosis in Norwegian maternity care and the challenges associated with the provision of these services, including counselling dilemmas and perceived differences in expectations between caregivers and expectant parents. There was notable diversity among these obstetricians in relation to their support of, and adherence to Norwegian regulations about the use of ultrasound, which indicates that the care pregnant women receive may vary accordingly.

Variability Over Time of Normal-Sized Fetal Renal Pelvis During the Second Trimester Scan.

PURPOSE: To investigate the variability of the normal-sized fetal renal pelvis (≤5 mm) over time and to analyze repeatability of measurements. MATERIALS AND METHODS: 98 fetal renal pelvises and 49 fetal urinary bladders were analyzed at a gestational age of 17-20 weeks at St. Olavs Hospital, Trondheim, Norway. The anterior-posterior diameter (APD) of the fetal renal pelvis and two diameters of the fetal bladder were measured with an interval of at least 30 min. Intra- and interobserver variations and variations over time and in association with bladder size were investigated. RESULTS: The mean difference in renal pelvis size between the first and second measurements was 0.09 mm (95% CI, -0.09 to 0.26 mm). The variation over time was ≤1 mm in 85% of cases and the renal pelvis was ≤4 mm in both the first and second examinations in 92% of cases. The intraclass correlation coefficient (ICC) was 0.54 (95% CI: 0.31 to 0.69). We did not observe any association between variation of bladder size and variation of APD. The difference in fetal renal pelvis size was ≤1 mm in 70% of observations for the first examiner and 58% for the second examiner. The intraobserver ICCs were 0.71 (95% CI: 0.62-0.78) and 0.60 (95% CI: 0.50-0.70) for the two observers respectively. The interobserver difference was ≤1 mm in 72% of cases and the interobserver ICC was 0.56 (95% CI: 0.34-0.71). CONCLUSION: The variation of the APD of the fetal renal pelvis over time was small in fetuses with the APD in the lower range and can mainly be explained by intraobserver variation.
